Format the system and install Windows 7 again. Meanwhile, A windows will popup which asks you to choose the method like quick format, NTFS Complete bla bla bla and you need to select NTFS method(Quick Format).

Shane, you can download this free software Gparted from sourceforge follow the instructions and "burn" the ".iso" file to a CD with another free program called Image burn .Run the CD at boot time ,you will be able to format the Hard Drive to NTFS. Take your time to look around the Gparted program to understand how it works ....Regards Fred

Super,
there are many software on gparted site but who is the software for me to format my hard disk....
or can u give the video tutorial to how to download the software and how to format disk.......

Shane,
Hello..Download the .iso file and save it to desktop or wherever you want... then run the previously downloaded and installed ImageBurn program....select the .iso that you just downloaded and "Burn" it to disk (CD)...Then load the disk to your new PC (Boot from the disk) and run the Gparted program to format the hard drive Regards Fred
